I've been testing individual MGSO mods for quite some time now. In the course of the Wiki page overhaul, I have created a new Wiki page which contains (or better: will contain) a full list of all mods MGSO includes.
As a future reference for people like me who desperately searched for the MGSO credits -- only to find the corresponding Wiki page filled with spam -- I upload a back-up of that particular site's content here.
